[LAD] Is it possible to use two RME cards in sync?

[Pau Arumí]

Hi,
i have another question to RME experts (hi Florian!).
the system i need to build should have 8 AES inputs and 24 AES outputs.
For that, i see two basic approaches 1) using two RME AES-32 (*) cards
in world-clock synch and 2) using a RME hammerfall with 24 ADAT
input/outputs and then several 8ch ADAT<->AES converters such as the
Aphex 144 (+), which costs about 400€ each 8ch unit.

Option 1 seems to me simpler and cheaper but i ignore if is feasible and
reliable: Have anyone had good experiences using two clock-synced RME
cards with jack?

Are there other options apart from 1 and 2?

Thanks a lot!
